Recording device and method of using the same



RECORDING DEVICE AND METHOD OF USING THE SAME Filed Sept. ll, 1925.ELECORDlNG 'BET/*EGE EID .fipsicanon slee sentences is.,

The invention relates to a checlrug or recording device and manner ofusing' 'the saine, objects of the invention heing to pro-` vide acheckup device and checkup system for determiningv the number of milestravcled., for example. by an automobile, between oiling and greasingperiods. rl`he device provides an arrangement for senaratelyrec cordingthe reading of an odometer, and maintaining such a record-reading forsub` sequent com'loarison with the total mileage readings ofi theodometer. For example,

" suppose that one Wishes to have the car oiled and greased after eachrive hundred miles ot travel. The recorder is set to correspond v/ithwhatever the total mileage reading of the odometer may be at the time.rlhereatter, as the odometer registers additional mileage, a comparisonmay always he had, so thatdiderence between the readings at any givenmoment will show the miles traveled since setting the recording device,and when this diiterence is shown to be, in this instance, live hundredmiles, oillng and ,gfreasing is in order.

Features of the invention include the use and arrangement of the checkupdevice ad jacent the odometer. as Well as the details ot const notion ofthe recorder or checkup device iper se.

another object is' to provide a recording device, the recording elementsor which are adapted to be set and to he locked in set posit-ion, by akey-operable means, to prevent change of the setting except byauthorized persons.

@ther objects and advantages will beset iorth in the description formingpart of this specification and in said drawings.

Figure l is a face view of an instrument board or cowl, showing myrecording device arranged adjacent an odometer;

Figure 2 is a vertical section of the recording de'vice;

Figure 3 is atop plan with portions ot the device broken away;

Figure i is a hottom view illustrating the arrangement of the loclrplate.

Numeral l designates the cowl or instrument board, 2 the odometer, and 3the casingof the recording device, attached as by holts si. The casingis provided in its forward side with a series of slots 5. Within thecasing, a shaft 8 isarranged lengthwise and suitably supported in theend Walls of the casing. Upon this shaft, are rotatably arranged SerialZio. 33113865.

a. series ci' dislrs l each having a nerinherally v j Y 1 4 I i frmnoi/cned plate 8 attached at its sine. ine dishshave peripherallyarranged numerals,

' and the nurnher of notches ofi the plates correspond to the number oinumerals, and spacing oi the saine. '.lho plates are concentric with theaxis ot rotation ot the disks and project through the slots forengagement, by the lingers, to rotate and set the saine. d fiat springl0, as a detent, is arranged to engage the notches of each plate toyieldably hold the disks in adjusted position, ande-ach plate afteradjustment is held by its corresponding springl until all plates arelocked against further adjnstment by a latch, now to he described.

lr latch shaft l2 is arranged in parallel relationv to lthe iirstmentioned shaft and at that side opposite the detente. This shaft has asquared end l lying Within the casing, and adapted for engagement hy ahey ld, 'through an openinol5. Upon the sha-lt is `mounted a plate 16aving an edge l? arranged for engagement vvith the notches 18,

when the notches oit all plates are aligned. A spring 2G is suitablyattached within the casing, and has one end engaged Twith one edge ofthe plate, frictionally, to yieldablj,T

secure the plate either in locked or unlocked f position, (see ignre 2).

My method oi using the device is as iollows:

The odometer reading is noted and then the disks of the recorder arerotated to bring into vien1 that sequence of numbers necessary toduplicate the odometer reading. The disks of the recording device arethen locked to maintain the record reading. The odometer record changeswith continued travel of 'the car, hut a comparison of the changedreadings with the recorder can be had any time; to show the number ofmiles traveled `since the recorder was set.

l claim as my invention:

1. A casing having therein -a series of notched disks rotatably mounted,a shaft within the casing having thereon a stop element movable in onedirection to engage aligned notches of the disks to prevent rotation,and a spring abutting one edge or' the stop on that side of the shai'topposite its disk-engaging portion in a manner to permit continued edgeengagement to secure the stop after a disengaging movement in anopposite direction.

2. A casing1 having therein a series oi Lili) Qi Lesage? notched disksrotatably mounted, a shaft having thereon a stop element movable toengage aligned notches of t-he disks to prevent rotation, and a springengaging one edge of the stop 1n a manner to permit continued edgeengagement to lsecure the stop after a disengaging movement 1n an op'-posite direction.

a. A easing having theiein a serles of notched disks rotatably mounted,a shaft within the casing having thereon a stop element movable toengage alignedv notches of the disks to prevent rotatlon, and a springengaging the stop in a manner to permit continued engagement to securethestop after a disengalling movement in an opposite direetion` saidspring' being secured at one end to the casing and having its free endengagging the stop.

4. A casing having therein a serles of notched disks rotatably mounted,a shaft Within the casing having thereon a stop element movable in onedirection to engage aligned notches of the disks to prevent rotation,and a spring engaging one edge of the Sto on that side of the shaftopposite its dis engaging portion in a manner to permit continued edgeengagement to secure the stop after a disengaging movement in anopposite direction, said spring being' secured at one end to the casing`and having its free end .engaging the stop, said shaft having an endlying Within the casing the end being formed to permit the shaft to beturnedby a key inserted through an opening in the casing.

In Witness whereof, I have hereunto set my hand this 4th day ofSeptember, 1926.
